Problems after update to core 159

new day and new hope to get my firewall back in it’s normal working order.
So far it seems like the last remaining issue is with the generating of graphs.

I can see this in the httpd/error_log every time i access a page in the webui that contains graphs.

(process:1457): Pango-WARNING **: 08:07:23.371: failed to choose a font, expect ugly output. engine-type='PangoRenderFc', script='latin'

(process:1459): Pango-WARNING **: 08:07:23.427: failed to choose a font, expect ugly output. engine-type='PangoRenderFc', script='common'

(process:1459): Pango-WARNING **: 08:07:23.429: failed to choose a font, expect ugly output. engine-type='PangoRenderFc', script='latin'

I changed the permissions of /etc/pango/pango.modules to 755 (was 644), but that did not change anything, even after rebooting the system.

Hope any of the experts can tell me if there is another folder that needs it’s permission adjusted.
